# ScientificNumberFormatter

`public final class ScientificNumberFormatter`
`extends Object` ``

java.lang.Object
↳ | android.icu.text.ScientificNumberFormatter

A formatter that formats numbers in user-friendly scientific notation. ScientificNumberFormatter instances are immutable and thread-safe. Sample code:

     ULocale en = new ULocale("en");
     ScientificNumberFormatter fmt = ScientificNumberFormatter.getMarkupInstance(
             en, "<sup>", "</sup>");

     // Output: "1.23456×10<sup>-78</sup>"
     System.out.println(fmt.format(1.23456e-78));

## Summary

### Public methods
`String` | `format(Object number)` Formats a number
`static ScientificNumberFormatter` | `getMarkupInstance(DecimalFormat df, String beginMarkup, String endMarkup)` Gets a ScientificNumberFormatter instance that uses markup for exponents.
`static ScientificNumberFormatter` | `getMarkupInstance(ULocale locale, String beginMarkup, String endMarkup)` Gets a ScientificNumberFormatter instance that uses markup for exponents for this locale.
`static ScientificNumberFormatter` | `getSuperscriptInstance(DecimalFormat df)` Gets a ScientificNumberFormatter instance that uses superscript characters for exponents.
`static ScientificNumberFormatter` | `getSuperscriptInstance(ULocale locale)` Gets a ScientificNumberFormatter instance that uses superscript characters for exponents for this locale.

### Inherited methods
From class `java.lang.Object`
`Object` | `clone()` Creates and returns a copy of this object.
`boolean` | `equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void` | `finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>` | `getClass()` Returns the runtime class of this `Object`.
`int` | `hashCode()` Returns a hash code value for the object.
`final void` | `notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void` | `notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String` | `toString()` Returns a string representation of the object.
`final void` | `wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void` | `wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void` | `wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

## Public methods

### format

    public String format (Object number)

Formats a number

Parameters
`number` | `Object`: Can be a double, int, Number or anything that DecimalFormat#format(Object) accepts.

Returns
`String` | the formatted string.

### getMarkupInstance

    public static ScientificNumberFormatter getMarkupInstance (DecimalFormat df,
                    String beginMarkup,
                    String endMarkup)

Gets a ScientificNumberFormatter instance that uses markup for exponents.

Parameters
`df` | `DecimalFormat`: The DecimalFormat must be configured for scientific notation. Caller may safely change df after this call as this method clones it when creating the ScientificNumberFormatter.
`beginMarkup` | `String`: the markup to start superscript e.g `<sup>`
`endMarkup` | `String`: the markup to end superscript e.g `</sup>`

Returns
`ScientificNumberFormatter` | The ScientificNumberFormatter instance.

### getMarkupInstance

    public static ScientificNumberFormatter getMarkupInstance (ULocale locale,
                    String beginMarkup,
                    String endMarkup)

Gets a ScientificNumberFormatter instance that uses markup for exponents for this locale.

Parameters
`locale` | `ULocale`: The locale
`beginMarkup` | `String`: the markup to start superscript e.g `<sup>`
`endMarkup` | `String`: the markup to end superscript e.g `</sup>`

Returns
`ScientificNumberFormatter` | The ScientificNumberFormatter instance.

### getSuperscriptInstance

    public static ScientificNumberFormatter getSuperscriptInstance (DecimalFormat df)

Gets a ScientificNumberFormatter instance that uses superscript characters for exponents.

Parameters
`df` | `DecimalFormat`: The DecimalFormat must be configured for scientific notation. Caller may safely change df after this call as this method clones it when creating the ScientificNumberFormatter.

Returns
`ScientificNumberFormatter` | the ScientificNumberFormatter instance.

### getSuperscriptInstance

    public static ScientificNumberFormatter getSuperscriptInstance (ULocale locale)

Gets a ScientificNumberFormatter instance that uses superscript characters for exponents for this locale.

Parameters
`locale` | `ULocale`: The locale

Returns
`ScientificNumberFormatter` | The ScientificNumberFormatter instance.
